Mini Live
Before connecting or disconnecting the power cord, make certain the ON / OFF switch is in the OFF
position.
Before switching on or off make certain the sound system’s amplifiers are off or turned down: this will
avoid signal peaks, which are annoying and sometimes dangerous (particularly for speaker
enclosures).
Do not connect (parallel or series) an amplifier output with any other amplifier output.
Do not connect this device to a dimmer pack.
Do not drive the inputs with a signal level bigger, than required to drive the equipment to full output.
Do not insert objects into air vents.
Do not open this device. Risk: hazardous radiation exposure.
Do not run the output of any amplifier channel, back into another channel’s input.
Do not switch the system on and off in short intervals, as this would reduce the system’s life.
Extreme frequency boosts in connection with a high input signal level may lead to overdriving your
equipment. Should this occur, it is necessary to reduce the input signal level by using the INPUT
control.
For replacement use fuses of same type and rating only.
If device is dropped or struck, disconnect mains power supply immediately. Have a qualified
engineer inspect for safety before operating.
If the system has been exposed to drastic temperature fluctuation (e.g. after transportation), do not
switch it on immediately. The arising condensation water might damage your system. Leave the
system switched off until it has reached room temperature.
In system setup, the amplifier's output power must be 50%-100% more than the loaded loudspeakers
rated power.
Keep this user’s manual for future consultation. Also remember that the crossover will get a better
price on the secondhand market if (as well as being in good condition) it has its original
documentation and packaging.
Make sure that the available voltage is not higher than stated on the rear panel.
Make sure that the power-cord is never crimped or damaged. Check the device and the power-
cord from time to time.
Make sure that the signals into the mixer are balanced, otherwise hum could be created.
Make sure that there is sufficient room on all sides of the system for air circulation.
Make sure you don’t use the wrong kind of cables or defective cables.
Make sure you use DI boxes to balance unbalanced signals; All incoming signals should be clear
Never let the power-cord come into contact with other cables! Handle the power-cord and all
connections with the mains with particular caution!
Never remove warning or informative labels from the unit.
Never use anything to cover the ground contact.
Only use device indoor, avoid contact with water or other liquids.
Please turn off the power switch, when changing the power cord or signal cable, or select the input
mode switch.
Prevent distortion! Make sure that all components connected to the DRX-Series have sufficient power
ratings. Otherwise distortion will be generated because the components are operated at their limits.
Repairs, servicing and electric connection must be carried out by a qualified technician.
Sometimes, when you want to send one signal to more than one amplifier, you should use a signal
distributor.
The best way (even if not always feasible) to avoid ground loops is to connect the electric ground of
all the equipment to a single central point (“star” system). In this case, the central point can be the
mixer.
To avoid or solve hum and buzzing troubles, try different combinations of lifting grounds on units that
are supplied with ground lift switches or make sure all chassis are connected to earth ground, either
through the A.C. power cord ground or by the front panel rack mount screws.
To emphasize a frequency range, you don’t necessarily have to move its respective sliding control
upward; try lowering surrounding frequency ranges instead. This way, you avoid causing the next
piece of equipment in your sound path to overdrive. You also preserve valuable dynamic reserve
(“headroom”)
WARRANTY: Till one year after date of purchase.
When connecting the other parts of your sound system, watch out for the so-called “ground loops”.
